    Translations help

    If A sub a = A sub b, then a=b. Hint: Apply translations to zero.

    Any advice?

    Sorry...A sub a is defined as a function Z ---> Z bu the rule x ---> x+a

    ...that was a very important piece of info, don't you think?

    assume  A_a(x) = A_b(x), then it means x + a = x + b. now what?
